Chapter 4 Module Configuration, Output, and Input Data
Output Overcurrent (Out0Overcurrent to Out3OverCurrent)
The output overcurrent bits are set (1) when the module is in an overcurrent
condition. These bits also show whether the output is latched off, because the
output remains in the off state and these bits remain on until the ResetBlownFuse
bit is used.
Module Configured (ModConfig)
Word 2, bit 5 is set by the module after it has accepted all of the configuration
data. When set (1), this bit confirms that the module received and accepted valid
configuration data. When reset (0), this bit indicates that the module still is
checking for errors or contains errors and the old configuration is still being used.
Invalid Output (InvalidOutput)
• 1 = an unused bit in the output array is set
• 0 = no unused bits in the output array are set
When this error occurs, the entire output array is rejected until an output array
that does not have this error is sent.
Error (GenError)
When this bit is set (1), it indicates one or more of the following errors for the
input array:
• OutnOvercurrent
• InvalidRangeLimitn
• InvalidCtrAssignToRangen
• InvalidOutput
• Ctr[n].Overflow
• Ctr[n].Underflow
• Ctr[n].InvalidDirectWrite
• Ctr[n].InvalidCounter
• Ctr[n].PresetWarning
where n indicates the counter number.
To determine which error has set the GenError bit, identify which bit is set. This
could be done by using a subroutine to examine these bits in the input array.
TIP
The module takes up to two seconds to validate configuration data.
TIP
Ctr[n].RateValid does not set the GenError bit.
